Description

차량 엔진의 냉각수 에어 배출시스템{Extracted air system in Cooling water of automotive engine}Extracted air system in Cooling water of automotive engine

본 발명은 차량 엔진의 냉각수 에어 배출시스템에 관한 것으로, 보다 상세하게는 공조장치의 블로우모터 작동시 발생되는 흡인력을 이용해 냉각수내 공기를 강제로 흡입시키도록 된 차량 엔진의 냉각수 에어 배출시스템에 관한 것이다.The present invention relates to a cooling water air discharge system of a vehicle engine, and more particularly to a cooling water air discharge system of a vehicle engine to forcibly suck the air in the cooling water by using the suction force generated during the operation of the blow motor of the air conditioner. .

일반적으로 차량의 엔진은 그 내부에서 발생되는 폭발력에 의해 회전 동력을 얻는 것으로 이와 같은, 엔진내의 폭발에 의해 엔진은 항상 고온으로 가열되므로 물을 엔진내로 순환시켜 엔진을 냉각시키게 되며 통상, 이와 같은 수냉식 냉각시스템은 엔진의 회전력을 이용해 냉각수를 펌핑하는 펌프와 엔진으로부터 배출된 고온의 냉각수를 식히는 라디에이터 및 엔진과 라디에이터사이로 냉각수를 순환시키는 배관라인으로 이루어지게 된다.In general, the engine of a vehicle obtains rotational power by the explosive force generated therein. Since the engine is always heated to a high temperature by the explosion in the engine, water is circulated in the engine to cool the engine. The cooling system consists of a pump for pumping the coolant using the rotational force of the engine, a radiator for cooling the hot coolant discharged from the engine, and a piping line for circulating the coolant between the engine and the radiator.

이때, 상기 배관라인은 엔진으로부터 배출되는 냉각수의 열을 이용해 차 실내를 난방 할 수 있도록 차량 공조장치인 히터를 거쳐 라디에이터부위로 이어지게 된다.At this time, the pipe line is connected to the radiator portion through a heater that is a vehicle air conditioning apparatus to heat the vehicle interior by using the heat of the coolant discharged from the engine.

그러나, 이와 같이 엔진과 라디에이터사이를 순환하면서 엔진의 열을 빼앗아 라디에이터를 통해 외부로 방출시키는 냉각수는 그 특성상 엔진의 열로 인해 에어를 함유할 수밖에 없고 이로 인해, 냉각수의 순환경로 중에 에어를 배출시켜주게 되는바, 이러한 에어 배출시스템은 도 1에 도시된 바와 같이 엔진(10)과 냉각수를 저장한 리저버탱크(20) 및 냉각수 열을 이용하여 난방하는 공조장치의 히터(30)사이에 구비되어진다.However, the coolant, which circulates between the engine and the radiator and takes out the heat of the engine and releases it to the outside through the radiator, cannot but contain air due to the heat of the engine, which causes the air to be discharged in the circulation path of the coolant. As shown in FIG. 1, the air discharge system is provided between the engine 10 and the reservoir tank 20 storing the coolant and the heater 30 of the air conditioner that uses the heat of the coolant.

즉, 엔진(10)을 식히면서 고온으로 가열된 상태로 배출되는 냉각수가 배출라인(40)을 매개로 히터(30)로 공급된 후 리저버 탱크(20)로 부터 냉각수를 공급하는 공급라인(70)에 조인트(70')를 매개로 연결된 복귀라인(50)을 통해 다시 엔진(10)으로 유입되고, 이 과정에서 상기 엔진(10)과 히터(30)사이를 연결하는 배출라인(40)에 상대적으로 작은 직경의 바이패스라인(60)을 조인트(60)를 매개로 리저버탱크(20)로 연결시켜 히터(30)로 유입되는 고온의 냉각수중 일부 냉각수를 배출하면서 공기도 함께 배출시키게 된다.That is, the cooling line discharged while being heated to a high temperature while cooling the engine 10 is supplied to the heater 30 through the discharge line 40 and then the supply line 70 for supplying the cooling water from the reservoir tank 20. It is introduced into the engine 10 again through the return line 50 connected through the joint (70 '), in the process relative to the discharge line 40 connecting between the engine 10 and the heater 30 By connecting the bypass line 60 having a small diameter to the reservoir tank 20 through the joint 60, the air is also discharged while discharging some of the coolant from the high temperature coolant flowing into the heater 30.

여기서, 상기 조인트(60')는 도 2에 도시된 바와 같이 배출라인(40)의 경로 상에 연결되면서 바이패스라인(60)이 함께 연결되는 티자형상의 어셈블리(60a')와, 이 어셈블리(60a')의 끝단에 구비되어 상기 바이패스라인(60)으로 배출되지 못하고 배출라인(40)내에 잔존된 공기를 외부로 배출하도록 분리되는 캡보올트(60b')로 이루어지되, 상기 어셈블리(60a')는 바이패스라인(60)이 연결되는 부위가 배출라인(40)에 연결되는 부위에 대해 소정 각도로 경사지게 형성되어지게 된다. Here, the joint 60 'is a tee-shaped assembly 60a' which is connected on the path of the discharge line 40 and the bypass line 60 is connected together, as shown in FIG. 60a ') is provided at the end of the cap bool (60b') is not discharged to the bypass line 60, but separated to discharge the air remaining in the discharge line 40 to the outside, the assembly (60a ' ) Is formed to be inclined at a predetermined angle with respect to the portion connected to the bypass line 60 is connected to the discharge line (40).

그러나, 이와 같은 냉각수 에어배출 시스템은 엔진(10)과 히터(30)사이의 냉각수 흐름 경로 상에서 일부 냉각수가 리저버탱크(20)쪽으로 자연스럽게 배출되도록 단지 우회 경로만을 형성한 것이므로 냉각수내의 공기 배출이 그리 크지 못하고 이에 따라, 상기 배출라인(40)과 바이패스라인(60)이 연결된 조인트(60')의 캡보올트(60b')를 분리해 인위적으로 공기를 외부로 배출시켜야만 되는 문제가 있게 된다.However, such a coolant air discharge system has only a bypass path so that some coolant is naturally discharged toward the reservoir tank 20 on the coolant flow path between the engine 10 and the heater 30, so that the air discharge in the coolant is not large. As a result, there is a problem in that the air must be artificially discharged to the outside by separating the cap ball 60b 'of the joint 60' to which the discharge line 40 and the bypass line 60 are connected.

또한, 이와 같은 냉각수 에어배출 시스템은 복잡한 엔진룸 상에서 공조단치의 히터(30)부위에서 리저버탱크(20)로 이어지는 바이패스라인(60)을 추가로 설치하도록 그 공간을 확보해야만 하므로 엔진룸의 레이아웃(Lay Out)에도 불리하게 됨은 물론이다. In addition, such a coolant air discharge system has to secure the space to install additional bypass line 60 leading to the reservoir tank 20 at the heater 30 of the air conditioning step in the complex engine room layout of the engine room Of course, it is disadvantageous to (Lay Out).

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 공조장치의 블로우모터의 회전력을 이용해 냉각수내의 공기를 강제로 배출시킬 수 있도록 함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and an object thereof is to allow the air in the cooling water to be forcibly discharged by using the rotational force of the blow motor of the air conditioning apparatus.

상기와 같은 목적을 달성하기 위한 본 발명은, 엔진으로부터 배출되는 고온 냉각수를 히터로 순환시키는 배출라인과, 상기 배출라인에 비해 상대적으로 작은 직경으로 이루어지면서 조인트를 매개로 배출라인과 서로 연결되어 공조장치의 작동 시 냉각수내의 공기를 강제 흡입시키도록 공조장치의 블로우모터를 통해 에어가 강제로 흐르는 통로인 송풍덕트쪽으로 연결되어지는 바이패스라인으로 이루어진 것을 특징으로 한다.In order to achieve the above object, the present invention provides a discharge line for circulating high-temperature cooling water discharged from an engine to a heater and is connected to the air discharge line via a joint while being made of a relatively small diameter compared to the discharge line. It is characterized by consisting of a bypass line which is connected to the blowing duct which is a passage through which the air is forced through the blow motor of the air conditioner to forcibly suck the air in the cooling water during operation of the device.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 따른 차량 엔진의 냉각수 에어 배출시스템의 구성도를 도시한 것인바, 본 발명은 엔진(10)으로부터 배출되는 고온 냉각수를 히터(30)로 순환시키는 배출라인(40)에 조인트(60')를 매개로 연결된 상대적으로 작은 직경의 바이패스라인(60)이 공조장치(80)부위로 이어지되, 상기 바이패스라인(60)은 공조장치(80)의 블로우모터(80a)를 통해 에어가 강제로 흐르는 통로인 송풍덕트(80b)로 연결되어진다.Figure 3 shows the configuration of the cooling water air discharge system of the vehicle engine according to the present invention, the present invention is a joint to the discharge line 40 for circulating the high temperature coolant discharged from the engine 10 to the heater 30 A bypass line 60 having a relatively small diameter connected through 60 'leads to the air conditioner 80, and the bypass line 60 connects the blow motor 80a of the air conditioner 80. It is connected to the blowing duct 80b, which is a passage through which air is forced.

여기서, 상기 조인트(60')는 단순한 티자형 연관 관으로 이루어지게 됨은 물론이다.Here, the joint 60 'is of course made of a simple T-shaped tube.

이하 본 발명의 작동을 첨부된 도면을 참조로 상세히 설명한다. 본 발명은 전술한 바와 같이 엔진(10)을 식히면서 고온으로 가열된 상태로 배출되는 냉각수가 배출라인(40)을 매개로 히터(30)로 공급된 후 리저버 탱크(20)로부터 냉각수를 공급하는 공급라인(70)에 조인트(70')를 매개로 연결된 복귀라인(50)을 통해 다시 엔진(10)으로 유입되는 순환 과정에서, 상기 엔진(10)과 히터(30)사이를 연결하는 배출라인(40)에 조인트(60)를 매개로 연결된 바이패스라인(60)을 통해 공조장치(80)의 송풍압력을 이용해 히터(30)로 유입되는 고온의 냉각수에 포함된 공기를 강제로 배출시키게 된다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings. As described above, the cooling water discharged while being heated to a high temperature while cooling the engine 10 is supplied to the heater 30 through the discharge line 40, and then the cooling water is supplied from the reservoir tank 20. In the circulation process flowing back to the engine 10 through the return line 50 connected through the joint 70 'to the line 70, a discharge line connecting between the engine 10 and the heater 30 ( The air contained in the high temperature cooling water introduced into the heater 30 is forcibly discharged by using the blowing pressure of the air conditioning apparatus 80 through the bypass line 60 connected to the joint 60 through 40.

즉, 도 3에 도시된 바와 같이 공조장치(80)를 작동시키게 되면 블로우모터(80a)가 회전되면서 에어콘이나 히터에 의해 발생된 냉기나 온기가 송풍덕트(80b)로 흐르면서 차량 실내로 토출되는데 이때, 상기 송풍덕트(80b)내의 압력이 블로우모터(80a)의 회전에 의해 저하되면서 바이패스라인(60)내의 압력과 배출라인(40)내의 압력 사이에 서로 압력차가 발생되고 이로 인해, 상기 배출라인(40)내에 포함된 공기가 조인트(60')를 통해 바이패스라인(60)으로 빨려나오게 된다.That is, when the air conditioning apparatus 80 is operated as shown in FIG. 3, the cool air or warm air generated by the air conditioner or the heater is discharged to the air blowing duct 80b while the blow motor 80a is rotated. When the pressure in the blower duct 80b is lowered by the rotation of the blow motor 80a, a pressure difference is generated between the pressure in the bypass line 60 and the pressure in the discharge line 40, and thus, the discharge line. Air contained in 40 is sucked into the bypass line 60 through the joint 60 '.

이에 따라, 상기 바이패스라인(60)을 통해 빨려나온 공기는 송풍덕트(80b)를 통해 차량 실내로 토출되어져 결국, 상기 배출라인(40)내에 포함된 공기가 블로우모터(80a)의 회전력에 의한 압력차로 인해 강제로 배출될 수 있게 됨은 물론이다. Accordingly, the air sucked through the bypass line 60 is discharged into the vehicle interior through the air blowing duct 80b, so that the air contained in the discharge line 40 is caused by the rotational force of the blow motor 80a. Of course, due to the pressure difference can be forced out.

또한, 본 발명은 냉각수내 공기를 배출하는 바이패스라인(60)이 공조장치(80)부위로 집중되어 배치되므로 전술한 종래의 경우와 같이 리저버탱크(20)쪽으로 위치시키기 위한 공간 확보가 요구되지 않으므로 엔진룸의 레이아웃에도 거의 영향을 주지 않게 됨은 물론이다. In addition, the present invention is because the bypass line 60 for discharging the air in the cooling water is arranged concentrated in the air conditioning device 80, it is not required to secure space for positioning toward the reservoir tank 20 as in the conventional case described above As a result, the layout of the engine room has little effect.

이상 설명한 바와 같이 본 발명에 의하면, 공조장치의 블로우모터의 회전력을 이용해 엔진 냉각수의 순환경로와의 압력차를 발생시켜 냉각수내의 공기를 강제로 배출시키게 되므로 공기의 배출성능이 좋음은 물론 에어배출 시스템이 공조장치부위로 집중되어 배치되므로 엔진룸의 레이아웃에도 거의 영향을 주지 않게 되는 효과가 있게 된다.As described above, according to the present invention, since the pressure difference with the circulation path of the engine coolant is generated by using the rotational force of the blow motor of the air conditioner, the air in the coolant is forcibly discharged. Since the air conditioner is concentrated and disposed, there is little effect on the layout of the engine room.
